谐波污染用户建模及危害评估

Modeled of Harmonic Pollution Users and Hazard Assessment

评估谐波污染用户危害及治理效果,首先需要建立合理的用户谐波污染模型,再从监测数据辨识模型参数,进而建立合适的危害评估场景,定义并计算谐波污染指标,最后评价用户对电网的谐波注入污染程度。文中论述了目前各种谐波污染用户模型的基本原理和特点,归纳了现有评估谐波污染的方法,分析指出了各种模型的适用性和各种方法的优缺点,并通过仿真比较分析了各种评估方法。

Assessment of harmonic pollution and treatment effect need to establish a reasonable user harmonic pol-lution models firstly,then identify the model parameters from the monitoring data,thereby establish an appropriate scene of hazard assessment,define and calculate the harmonic pollution index,at last evaluate harmonic pollution levels of the user in power grid. This article discusses the basic principles and characteristics of user harmonic pol-lution models,summarizes the existing assessment methods of harmonic pollution,analyzes and points out the ap-plicability of the models and the advantages and disadvantages of each method,then compares and analyzes the as-sessment methods by simulation.
